python获取网络时间和本地时间

今天我们来看一下如何用python获取网络时间和本地时间，直接上代码吧，代码中都有注释。

python获取网络时间

获取网络时间
 def getBeijinTime():
     \"\"\"
 　　 获取北京时间
     \"\"\"
     try:
         conn = httplib.HTTPConnection(\"www.beijing-time.org\")
         conn.request(\"GET\", \"/time.asp\")
         response = conn.getresponse()
         print response.status, response.reason
         if response.status == 200:
             #解析响应的消息
             result = response.read()
             logging.debug(result)
             data = result.split(\"\\r\\n\")
             year = data[1][len(\"nyear\")+1 : len(data[1])-1]
             month = data[2][len(\"nmonth\")+1 : len(data[2])-1]
             day = data[3][len(\"nday\")+1 : len(data[3])-1]
             #wday = data[4][len(\"nwday\")+1 : len(data[4])-1]
             hrs = data[5][len(\"nhrs\")+1 : len(data[5])-1]
             minute = data[6][len(\"nmin\")+1 : len(data[6])-1]
             sec = data[7][len(\"nsec\")+1 : len(data[7])-1]
              
             beijinTimeStr = \"%s/%s/%s %s:%s:%s\" % (year, month, day, hrs, minute, sec)
             beijinTime = time.strptime(beijinTimeStr, \"%Y/%m/%d %X\")
             return beijinTime 
     except:
         logging.exception(\"getBeijinTime except\")
         return None

python获取本地时间

同步本地系统时间
 def syncLocalTime():
     \"\"\"
     同步本地时间
     \"\"\"
     logging.info(\"current local time is: %d-%d-%d %d:%d:%d\" % time.localtime()[:6])
      
     beijinTime = getBeijinTime() 
     if beijinTime is None:
         logging.info(\"get beijinTime is None, will try again in 30 seconds...\")
         timer = threading.Timer(30.0, syncLocalTime)
         timer.start();
     else:
         logging.info(\"get beijinTime is: %d-%d-%d %d:%d:%d\" % beijinTime[:6])
              
         tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec = beijinTime[:6]
         import os
         os.system(\"date %d-%d-%d\" % (tm_year, tm_mon, tm_mday))     #设置日期
         os.system(\"time %d:%d:%d.0\" % (tm_hour, tm_min, tm_sec))    #设置时间
         logging.info(\"syncLocalTime complete, current local time: %d-%d-%d %d:%d:%d \\n\" % time.localtime()[:6])
